Flywheel nut fits 4500 (45cc), 5200 (52cc) and 5800 (58cc) Chinese chainsaws and also Plantiflex, BBT, B&Q, Silverline, Sanli, Whitemoss, Skatco, Eckman, Timbertech, Tarus and MT-9999 chainsaws. The flywheel nut threads onto the end of the crankshaft and clamps the flywheel securely onto the crankshaft taper, holding it in the correct position during engine operation. A stripped, rounded or missing flywheel nut makes it impossible to torque the flywheel properly — leaving the flywheel loose on the taper, which causes it to shift under load and disrupts ignition timing. Replacing a damaged nut with a correctly threaded replacement ensures the flywheel is held firmly in place and the engine runs with accurate timing.
